Oathbinding

This spell binds the subject to certain vows and conditions, and stipulates a penalty for failing to meet them. Although similar to a genie contract, the oathbinding spell binds only one party, not two. This is often offered by a stronger party in return for a favor or as an alternative to some more severe punishment. Such a binding must have a definite end or condition under which it is broken. A dispel magic or remove curse will not counter it. An oathbinding cannot compel extreme changes in behavior or bind the subject to lengthy servitude. Since the spell is voluntary, magic resistance is not a factor.

For example, in Arabian lands, if a wizard accepts such a binding (for example, to slay no djinn for a year and a day), a genie may undertake voluntary service for the wizard for a limited time or a limited number of occasions.

The spell requires the caster to sacrifice at least 1,000 gp to a sealing power.

Notes: Uncommon spell, originally from an Arabian setting.
